How to make your work more safe and sound?

Hi Before working for any job, my suggestions are below to make safe your work from fraud buyer and some detector points may help you as seller for safe work:

1. First response to buyer after ordering
2. Go to buyer profile
3. And check buyer join date. If buyer joined few days or month before but he has profile percentage 0% as level 1, it is okay.
4. Check as buyer user level. If he/she level 1 or 2 or 3 or other but has 100% buyer rating, you can note it for good buyer
5. If you see buyer level 2 or 3 but buyer percentage 0% note it, something there wrong
6. If you see buyer join 1 or 2 years before even more but level 1 with 0%. Note it, he is ordering irregularly but genuine
7. Look buyer flag. And note it. Some specific countries buyer mostly do fraud. Observer trend.
8. if buyer level 1 -3 but before placed order from you. Proceed for him without tension.
9. If buyer user level 2-3 but buyer percentage 90% up. Note him as strict buyer
10. If buyer level 1 -3 but 50-60% buyer level. Note it he frequently leaving thumbs down
11. If you see buyer level 2-3 but buyer percentage less then 50%. Be couscous for doing job for him
12. If buyer has dispute history, avoid him
13. If buyer communicative, no problem for doing his job even 0% profile
14. If buyer has ordering history before from you and level 2-3 but 0% profile and did not get any feedback from you too. Please leave a short feedback at least, suddenly you can see buyer current rating percentage.
15. If your buyer working as seller on Seoclerks, note him as strict buyer
16. If your buyer working as seller and he has same service which ordering you. e.g. he has bookmarking service and he also ordered you for bookmarking. So, before working ask him why he makes order for you for same service? If you get good response then you can proceed, either think first, what is better for you?

If you try to insist on above points. Hope your work will be more safe.
But all points will not work anytime. Sometimes it may different.

Note: Sometimes buyer level 1-3 but percentage 0% he may excellent buyer too, May be he did not get any feedback from any seller.
Or He does not know how to leaving feedback to you and you missed too for leaving feedback him.

My information not 100% correct but you can note it. Hope it will help to safe your work.

If anybody has more suggestion add below.
